Abstract

A filter for a cigarette has a porous filter rod with a channel extending longitudinally through the filter rod. The end of the filter at the tobacco column of the cigarette includes a partition having an orifice therethrough of a smaller cross-sectional area than the cross-sectional area of the channel to provide flow communication between the tobacco column and the channel. The partition further provides for the flow of smoke from the tobacco column into the filter wherein the smoke is diluted as it is being filtered by ventilation air entering the filter rod through an air permeable material circumscribing the filter rod.
